Galvanizing is the practice of submerging iron or steel into molten zinc at 450 C. to form a zinc coating. The zinc is metallurgically bonded to the materials surface which protects against corrosion in 2 ways;
There are 3 steps in the galvanizing process:
Surface preparation consists of cleaning the steel to remove oxides and contaminates such as grease, dirt, rust and scale. The material is then submerged in a flux bath to cease the oxidation of the material.
We have 7 different tanks that can be used depending on material properties:
Dimensions of the tanks: 60’’ wide X 42’ long X 8′ deep.
The material is now ready for galvanizing. Once the steel is submerged in the zinc tank and the material reaches the temperature of the molten zinc, it is slowly removed to allow proper drainage of any excess zinc. It can be dipped with a racking system or by way of centrifugal process for smaller pieces.
The galvanized pieces are then inspected for any required filing (drainage locations) and packed accordingly to match the order at time of reception.
